Drug Testing Services NC

Pre-Employment Drug Testing

  • Pre-employment drug testing is the most common type of drug test used by businesses.
  • It is the least expensive type of testing, since the company only pays for one test per employee.
  • Most pre-employment drug testing is urine-based which can run the risk of adulteration or substitution, but is the least expensive option.
  • Pre-employment testing is a good preemptive measure to ensure a drug-free workforce, but further testing is recommended as a deterrent against a developing drug problem.

Random Drug Testing

  • Random drug-testing is used by corporations, drug rehabilitation centers, prisons, the military, police and fire departments, government agencies, and schools.
  • This method of drug testing serves as a risk deterrence, as the threat of detection is much higher than other testing methods.
  • The goal of random drug testing is to discourage drug use within work and educational environments.
  • Random testing is more likely to catch marijuana users, since it has a longer duration in the body than those of other drugs.

Post-Accident Drug Testing

  • The point of this test is to protect the company from liability in the event that the individual is under the influence at the time of the accident.
  • If drugs or alcohol are detected, the argument can be made in court that the individual was intoxicated on the job, and therefore the company should not be held liable for injuries sustained by the employee.
  • This argument can only be made with blood or oral fluid/saliva tests. Urine or hair testing can only detect past drug use.
  • If an employee shows up for work intoxicated, has alcohol on his or her breath, or appears to be impaired in some other way, these tests can protect your company from litigation.

Reasonable Suspicion

  • This type of testing is a confirmation method for employers that suspect an employee of being under the influence of drugs or alcohol while on the job.
  • If a supervisor suspects an employee of being under the influence and has appropriate evidence or has been certified in Rapid Eye behavioral examination, the suspected employee should be driven by an employer representative to and from the testing facility for safety.
